A new study by the University of Portsmouth and University of Surrey in England has identified the link between being an “evening person” and problematic technology use.

Four out of five parents tell their donor-conceived children about their biological origins.

Cervical cancer is the fourth most common cancer among women globally, according to the World Health Organization. It accounted for 660,000 new cases and 350,000 deaths in 2022.

Screening, along with early detection and treatment, can greatly improve a patient’s chances of survival. But in low- to middle-income countries, many women are not being screened, and they’re disproportionately dying from the disease.

In new research from Texas McCombs, Anima Nivsarkar, a doctoral student in marketing, uncovers a powerful tool to boost screening: trust. When messages are delivered by trusted and credible sources such as doctors and peers, they increase the likelihood that women will seek potentially life-saving exams.

In a series of studies, researchers from the United States, Ukraine and beyond show how everyday people and communities banded together to keep the nation running in the midst of war. 

Zebra finches can not only distinguish the full range of their species’ vocalizations but also organize them by meaning, according to a new study. The results suggest a surprising level of semantic understanding in the birds. Many social animals use a rich repertoire of vocalizations to communicate their needs, emotions, and awareness of the environment. Researchers have long tried to decode these sounds – essentially the species’ “language” – by grouping them into call types based on how they sound, the situations in which they are used, and how other animals respond. However, it is unclear whether these categories reflect the animals’ own perception or understanding of meaning. Zebra finches, highly social songbirds that use around 11 distinct call types for diverse social behaviors, offer a useful model to evaluate these questions. To test how adult zebra finches classify their species’ vocalizations, Julie Elie and colleagues performed an experiment involving 12 finches, in which the birds had to distinguish one rewarded call type from the other ten nonrewarded call types, including those from other, unfamiliar species. Elie et al. found that these birds have a remarkable ability to distinguish all call types in their vocal repertoire, demonstrating that they can accurately perceive and categorize their species’ vocal signals. Importantly, the authors found that call “misclassifications” were more common between call-types used in similar behavioral or social contexts, suggesting that zebra finches organize calls semantically and form mental representations of their underlying meanings.
